getting that really uneasy feeling (nfl 2008, and draft)

so many mock drafts from 'experts' (for what their opinion is worth, considering i destroyed most of them in the weekly pickems  )  have all the good  OL  gone by the time the steelers pick comes up 1st round.  now sure, there are miracle late round finds (larry allen, anyone?) but these mocks have them taking either stewart at RB (a very underrated player IMHO, but not a spot we 'need')  or  balmer @ DT  (this is a spot where there is 'moderate' need, and he projects to play DE as well).    however, if they don't get 2 quality OL before the year starts, big ben will be knocked out of the NFL for good, by week 10, guaranteed-- i just really don't see how they do this.  i would actually like them to just trot out charlie batch, throw all 16 games, and get 2 awesome picks next year for OL.
